Redmine

Trying to get it running again (from deb repos, vanilla working mysql/redmine), have chowned www-data.www-data the /var/www/redmine symlink which point to the same place as old public folder at /usr/share/redmine/public, enabled passenger, restarted apache2, /etc/apache2/sites-available/redmine looks like:

<Directory /usr/share/redmine/public>
        Options -MultiViews
        RailsBaseURI /redmine
        PassengerResolveSymlinksInDocumentRoot on
</Directory>

http://blah/redmine just lists directory contents of /usr/share/redmine/public/

where should I be looking. My mysql db contains all the data it did prior to the upgrade, and my db connection still works with redmine user/pwd.
